What does the 1.45 A/R ratio mean for performance?

A 1.45 A/R ratio is considered a larger housing size. This generally means it will help the turbocharger produce more top-end power and sustain higher boost levels at higher RPMs, though it might spool up slightly later compared to a smaller A/R housing.

Why is stainless steel used for this turbine housing?

Stainless steel is used because it offers excellent resistance to the extreme heat and corrosive exhaust gases produced by an engine. This material choice contributes to the housing's durability and longevity in a high-performance turbocharger application.

What is the significance of this part not being CARB approved?

This means the turbine housing does not meet the emissions standards set by the California Air Resources Board (CARB). As a result, it cannot be legally shipped to or installed on vehicles registered in California.

Product Details

This is the TiAL Sport BWVB96145-1.45 A/R S400 turbine housing, designed for a 96mm turbine wheel. It features a 1.45 A/R ratio, which helps manage exhaust gas flow for optimal turbocharger performance. This housing is constructed from stainless steel, offering good resistance to the high temperatures and corrosive elements found in exhaust systems.

The 1.45 A/R ratio is on the larger side, meaning it's intended to help the turbocharger spool up a bit later but sustain higher boost levels and power output at higher RPMs. This makes it a solid choice for builds focused on top-end power, especially when paired with larger engines or those seeking significant horsepower gains. The stainless steel construction is a notable detail, as it's well-suited to handle the extreme heat cycles of a performance turbo setup, contributing to its longevity and reliability under demanding conditions. This housing is designed to fit the S400 frame turbocharger, a popular choice for many high-performance applications.

Please be aware that this part is not CARB approved and cannot be shipped to California. If you are building a high-performance engine and need a turbine housing that can handle significant exhaust flow and support substantial power, this TiAL Sport housing is a well-built option. Always refer to your specific turbocharger's documentation and your engine build plan to ensure this housing is the correct match for your goals.
